The advantage of Google books is that it permits a deeper search into the contents of books than is possible in, for example, Library Search. The Google book search trawls the full text of the books that have been scanned within the project.
Having found a book chapter which is relevant using Google book search, it is then possible to search Library Search again in order to discover whether that book is in the University of Westminster collection, either in print or electronic form.
It is not permissible to print or save from the Google book results.
